Be it known that we, ORLANDO R. Enwiiv and C'Unris B. FLORY, citizens ot the United ftates, and residents ot New York city, in the county of Queens and State of New York, have invented certain new and useful Improvements in F ireExtinguishing Apparatus, ci which the following` is a specification.

@ur invention relates vto fire extinguishing apparatus ot the type employinga plurality or' separate receptacles containing s0- lutions which, when intermingled, produce a tenacious l'oain; and is particularly directcd to improvements in the means for produciiig suitable pressure in the receptacles ior delivering the solutions to the point or' intermixture ot application to the lire, this application being tor the most part acon tinuation of our former application iiled November 19, 1917, Ser. No. 202,17 28.

A primary characteristic inherent in the vroam system or extinguishing` rires-is the fact that neither solution is employed directly for extinguishing lire, the solutions being iiitermingled at a suitable mixing station and losing their identity in the reaction, producing the foam which is applied tothe fire. rl`his lcharacteristic makes it lnecessary to` provide means for forcing each solution separately to the mining point, an operation heretofore accomplished by injecting compressed air or steam into the solution vcontainers. However, such an arrangement requires the employment oit special 'apparatus 'for compressing the air or generating steam, and is firticularly disadvantageous with the portab e type or' extinguisher.

A principal object of our inventionis to providesimple and Compact means :tor applying said pressure to the separate containers, eliminating the bulky and compliacated apparatus heretoitore employed. A further object is to produce a construction suitable for use `with `either stationary or portable apparatus, and which may be applied to the latter without materially in- `creasing the bulk or weight thereof.l

A specific object is to provide apparatus for producing delivery pressure in the corry taiiiers operated entirely by the interaction of the solutions, eliminating the necessity `for and employment ot external sources of energy. This feature is highly advanta- FIRE-EXTINGUISHING APPARATUS.

geous, not only with portable apparatus,v

which is thereby enabled to operate in any location without the use of portable engines or manual labor tcrproducing pressure, but also in connection with stationary installations, which maybe located at any desired point independent of sources ot power for producing pressure, and without the concurrent installation and care of a power plant.

i further object is to provide a system cl this type in which the deliverv pressure can be readily varied and controlled. i also disclosed a construction where the containers may normally be maintained at any desired pressure ranging from that of the atmosphere to and beyond the maximum dclivery pressure. Furthermore, we have dcvisedmeans whereby the pressure in the containers may be raised very rapidly to that necessary for the delivery ot the solu tions to the mixer and the propulsion of ther foam onto the lire, thereby producing an apparatus which may be put into operation almost immediately 4without elaborate and lengthy preparation, a highly important feature iu lire-lighting devices. Y

Other objects and advantages of my invention will be apparent from the following description, taken in connection with the acA companyiiig drawings, in which:

Our invention is applicable to systems of the foam type, in which a plurality of solutions are normally stored in independent containers. Forv convenience, l have illus* trated a system of the ordinary two-solution kind, in which each solutionl is nor- We havev tainer, such as Atanks and 11.

Pulverized soap bark pounds.

Solution B IQ gallons.

Water 88 gallons. Aluminum sulphate" 615 pounds.

- As' heretofore indica-ted, means is provided for conducting'each solution from its container to a suitable mixing station. 1n the construction shown in Fig. 1, we employ a suitablepipe line 12 having an inlet 13 adjacent the bottom of tank 10, and extending therefrom into a suitable mixing chamber 14 preferably located outside of the solution containers. A similar pipe line l5 extends from an inlet 16 in tank 11 and adjacent the bottom thereof to the mixing chamber 14.

' We employ means for conveying the foam produced in chamber 14 to a suitable point for application to the fire, such as hose 17. Inletsl and 16 may be adapted to prevent solid matter from entering pipe lines 12 and 15, as by theemployment of a suitable screen arrangement lwhich may be in the form of a perforated pipe as shown.

In general, we develop a suitable delivery pressure in the solution containers by mixlng a relatively small portion of the solution from tank 10 with a suitable amount of the solution from tank'11, and applying the pressure resulting from the expansion of the intermingled liquids to both tanks 10 and 11, the apparatus for accomplishing this object being independent of thatA employed in conveying the separate solutions to the mixing point, such as chamber 14. One eonvenient and simple method of accomplishing this object consists in introducinga portion of the solution from one container into contact with the solution in the other container', developing pressure at the latter point, and providing means for conveying such pressure to the lirst container.

This arrangement is disclosed in Fig. 1, in which we employ a suitable passage be` tween tanks 10 and 11, such as piping 18, provided with a normally open inlet 19 1n tank 10 and preferably adjacent the bottom thereof, and a suitable outlet 20 in tank connecting therewith and to shield outlet 20 in a similar manner, by a perforated pipe section 22. Either or both of the perforated pipe sections 21 and 22 may extend a substantial distance into the respective solutions to promote rapid and infallible operation. f

le provide means for introducing a portion of the solution from one container into the other when the development of pressure is desired. One construction suitable for the purpose includes the arrangement of tanks 10 and 11 in such a position that the normal effect of gravity will cause the solution from one tank, such as tank 10, to flow through piping 18 into the other tank 11. When this arrangement is used, we proA vide means for normally closing the connection between the tan (s, said means being of such a nature that it may be readily opened when pressure is desired. One convenient form is operable manually, and may consist of an ordinary valve 23. in piping 18, provided with a handle 24 whereby the valve may readily be opened and closed at will.

With this construction, it will be apparent that tanks 10 and 11 may normally be maintained at atmospheric pressure until thek apparatus is needed for use, when the opening of valve' 23 to a suitable extent by manipulation of handle 24 will permit a portion of the acid solution to flow from tank 10 into tank 11, where it will interact with the alkaline solution therein, the resulting `expan sion raising the pressure in tank 11 proportionately to the amount of acid solution introduced thereon. As a result, the alkaline solution in tank 11 is forced through piping 15 to the mixing chamber 14.

We provide means for transmitting to tank 10 the pressure developed in tank 11,

so that the acid solution may be forced simultaneously to the mixing point. This result is conveniently accomplished by conl beinglr important in a foam system, as the character of the foam is more or less dependent upon the intermixture of the component solutions in` predetermined regulated pro-` portions. Moreovor, the pressure generated canbe 'varied at Will by manipulation of valve 23, providing complete and ready control of the mixture and propulsion of foam.

In the specific embodiment shown in Fig. l, We have found it convenient to mount the acid tank i() directly above the alkali tank ll', as less acid than alkali is required in the production of foam according to the formula set forth in the above mentioned patent to Erwin et al No, 1,225,944@ and the tanks and solution conveying system are proportioned accordingly. The tanks may be mounted upon a suitable portable trame 26, and each tank is preferably provided with a tilling opening 27, which normally is sealed by any suitable means, such as cap 2S.

The piping systems connecting tanks 10 and 1l with the mixing station, When tree 'from valves as in the lform disclosed in Fig.

l, should of course rise at some point above the level oi the respective solutions to prevent the flow thereof into'the mixing chamber in the absence of delivery pressure in the tanks, the piping systems 12 and l5 in the form disclosed extending from the top of each tank for this purpose.

`The apparatus shown in Fig. 2 is in general of the same type as that disclosed in Fig. l, being of the portable type; and is shown as provided with the same means for generating delivery pressure in the tanks l0 and il. However, the apparatus is adapted Ator use With mixing means located at some distance, this arrangement being desirable where the tank 10 cannot be positioned immediately adjacent the lire, since the foam tends to loseits eiiiciency when transported `for a long distance, unless the piping employed is of a size so large as to be impractical in connection With a portable apparatus.

TWe have illustrated an apparatus adapted 'for connection to a fixed installation which includes a mixer; and consequently the pipe lines l2 and l5 do not connect at the apparatus, but communicate with means tor connecting said lines to the lixed mixer. Various arrangements for this purpose can obviously be employed, the one illustrated including lhose lines 29 connected to pipe lsystems 12 and l5, and adapted for ready cou-i pling to lixed pipe connections 30 leading into the mixer 3l. It desired, valves 32 may vbe inserted in pipe lines l2 and l5 to facilitate control. of solution flow Without diminishing the pressure in the tanks 'i0 and il, and similar valves may be carried by the fixed installation connected to mixer 3l. ln the form shoivn, this installation is mounted on a tank 34,- ot the type generally used Yfor the storage of oil, and is provided With a riser 35 extending from mixer 3l to a point near the top of the tank 34, Where outlet 36' directs the foam onto the surface of the tank contents. This type -ot installation, however, is only one of various forms known to those skilled in the art, and is shown primarily for purposes ot illustration.

One convenient construction for mixer 3l is shown in Fig. 3, in which the solution pipes 30 communicate with a mixing chamber 37, which connects With the riser 35, pipes 30 being of diii'erent diameters if desired, so that the component solutions Will be introduced into chamber 37 in proper proportions.

ln Fig. i We have shown one arrangement by which our invention may be applied to a lixed installation system. ln this arrangement, We have shown construction generally similar to that ot Fig. l, tanks l() and ll being mounted in tixedposition. Certain variations in details have been disclosed, however, such as the extension oi? the pressure-equalizing pipe system 25 trom tank ll directly upward through the bottom of tank 10, terminating inside of and adjacent the top of the latter tank. @ne other variation includes the provision oiz a perforated inletpipe 2l along the bottom of tank i0, and a connection between pipe system l2 and tank l0 at the bottom of the latter, this arrangement being convenient Where tank 11 is below the surface of the ground, tank 10 above the surface, and the piping systems are located on a. plane between the tanks, as in the form illustrated. rlfhis arrangement, hoW- ever, calls for the employment oi valves 32 toprevent the interminglingot the solutions under normal conditions.

llig. 4 shoivs various connect-ionsl which may be made between the iixed dual supply lines 'i2 and i5. At the lett, ive have shown the dual system as connected in the general manner` shown in F 2 to a similar `mixer 3l communicating With a 'loam 'supply line which extends to any suitable dispensing device, the line sho-Wn being connected with laterals 39 extending to the upper part of tanks Se and operating in substantially the manner described in connection with Obviously, suitable valves 82 may be employed in controlling the ilow ot the solutions, and valves 4:0 inserted bet-Ween the foam line 38 and` laterals 39.

Another arrangement, in which the tivo lines are delivered separately practically `to the point of application to the fire, is shown at the right of Fig. el, in which later-als 'al communicate with the distribution pip-ing systems l2 and l5 and terminate ata mixing station, Whichmay be of the form shown in Fig. 2. Valves a2 preferably control the connections between the distribution lines and laterale al.

Another dispensing arrangement suitable for` use with this type or" system is alsoy shown in said system, and includes the valve controlled outlet i3 to which a est may readily be attached.

While we have disclosed various arrangements for distributing and dispensing the solutions and foam in a :Hired installation of this type, it will be apparent that these 'forms are merely illustrative, as obviously a great many other connections, systems and arrangementsmay be employed in conjunction with the dual distributing systems 12 and 15; and our invention is not restricted to the types disclosed or to mere variations in details thereof.

Another construction embodying our invention is illustrated in Fig. 5, and is shown as embodied in a portable apparatus with tanks 10 and 11 mounted on a wheel-supported trame 45. In this form, the pressure equalizing pipe 25 entends from tank 11 upwardly through lthe bottom o'l tank 10, in substantially the same way as in Fig. d, and terminates above the gei'ieral level ot the top of tank 10 in a suitable housing or dome 46. Ne also may employ a safety valve .t7 which` may be mounted on dome 426. In this form, inlet 19 opens directly trom the bottom ot' tank 10, and is protected from clogging by a. screen 48. ln this construction, we have found it convenient to extend the valve stem or handle 2li rearwardly along tank 11 into ay position where it may readily be manipulated by the operator, without interference with tanks 10 and 11. The outlet piping systems 12 and 15 are shown as provided with screen-covered bell mouth inlets 49, said systems communicating with the two members olf a dual hoseline 50, which may be connected to any suitable mixing and dispensing means, such as nozzle 51, preferably similar in construction to that disclosed in the patent to lllalker No. 1,299,272.

Vhile we have disclosed several variations in a dual tank system, all of the forms above described are provided with tanks arranged on diii'erent planes, so that a solution may flow by gravity from one tank to the other. Such forms also show one of the tanks as serving not merely for the storage ot solution, but also as a mixing reservoir to gencrate delivery pressure. Our invention, however, is not limited to either oft these arrangements; and in Figs. 6 to 8 we have shown a few oit the numerous modifications in the arrangement of the tanks and the connections therebetween, and the mixing apparatus which may be employed within the scope oi' our invention.

In Fig. 6 we have disclosed tanks 10 and 11 arranged horizontally; but owing to the difference in size ot the tanks in this specific form, the lower portion ol' tank 10 is sutilciently above the bottom ot tank 11 so that the piping system 18 connecting the bottoms of the tanks will be at such an angle that the acid solution will readily ilow from tank 10 into tank 11 when valve 23 is opened.

rlhe pressure equalizing pipe 25 connects the upper portions or" the tanks in the manner heretofore described, and may have a valve 52 for controlling the transmission of pres sure from tank 11 to tank 10, in case the solution in the latter tank should by any mischance be withdrawn more rapidly than that in tank 11.

ln Fig. 7, the tanks are also arranged in substantially horizontal alinement, with a pressure equalizing pipe 25 arranged similarly to that shown in Fig. 6. We have, however, disclosed a construction in which the pressure is generated not by transfer of a solution from one tank to the other, but by the introduction into a tank of a suitable 'fluid tromv a separate container 53, the interaction of such fluid with the solution in the main tank producing anexpansion of materials and a resultant pressure similar to that above described. The solutionin container 53, which is shown as communicating with tank 11, may be the same as that normally in tank 10; and in the form disclosed, the container 53 is mounted above tank 11 and connected therewith 4by a suitable piping 54 containing a valve k55 which, when open, will permit the fluid to flow from said container into tank 11.y

An arrangement of a similar nature is shown in Fig. 8, the pressure-producing fluid being carried bya container 56 of a portable type adapted to be connected to one or the tanks, for instance tank 11, as by flexible hose 57 the container 56 being provided with a suitablepump or plunger construction actuated by handle 58 and adapted to force the fluid from the container56 into tank 11 when and as required.

Various other modiiications may readily be substituted for those shown; and in parf ticular, our invention is not restricted to the employment of one of the main lluid containers as a mixing chamber. Moreover, while the specific forms described employ the actual solutions used in generating foam to produce the expansion which is employed in exerting delivery pressure, this arrangement may be varied, and other chemical agents may be utilized, either acting upon one of the main solutions or upon each other, to generate gas which is applied equally to the main solution containers 'for developing delivery. pressure therein. For instance, suitable carbonatos may be introduced into the acid container to generate carbondioxid gas therein, without the production of foam, as is the case when gas is generated in the alkali solution of the type disclosed in the said patent to Erwin et al. Furthermore, while the systems now in general use employ only two solutions, it will be apparent that it a three-solution system is found useful, our invention is equally applicable thereto, as the pressure may be communicated withl equal` facility to any numberof containers bysuitable arrange.

ment of the equalizing piping system 25.
